MSP432E401Y: Timestamp module does not work with Timer driver module

Hi Stefan,

Is there a specific example project you imported from the SDK? Is the SDK you are using 4.20.00.12 at https://www.ti.com/tool/download/SIMPLELINK-MSP432E4-SDK?

Hello Srinivas,

Thanks for your reply. Yes I am using SDK 4.20.00.12. 

I found a work-around solution by keeping CONFIG_TIMER_0 reserved and instead creating a new one, which does not return NULL. 

Is there some mysterious connection between the Timestamp module and CONFIG_TIMER_0?

Hi Stephan,

I wanted to follow up on your question. I suspect that something else in your code is already using the Timer_0 module, so when the Timer_open() function is called by the timestamp code, a NULL is returned since the timer resource is already in use. In CCS, I started with the timerled code example under TI Drivers in TI Resource Explorer, and the Timer_open() function did not return NULL since the Timer_0 module was initialized by Timer_init() and was available. In this example, Timer_0 is used to blink the LED. You may also want to check the SysConfig settings as well.

I hope this helps.
